Featured in PASCO’s Chemistry through Inquiry Teacher Guide
Features over 25 inquiry based labs covering the fundamental concepts of lab skills, structure & properties of matter, chemical reactions and more.
Ideal Gas Law
Use an absolute pressure sensor and stainless steel temperature sensor to
determine the number of moles of carbon dioxide gas generated during a reaction between hydrochloric acid and sodium bicarbonate.
Determine the number of moles of carbon dioxide gas generated during a reaction between hydrochloric acid and sodium bicarbonate. Through this investigation, students:
- Apply the ideal gas law (PV = nRT) to experimentally determine the number of moles of carbon dioxide gas generated.
- Use the balanced chemical equation and stoichiometry to calculate the theoretical number of moles of carbon dioxide gas generated.

Sample Teacher Information (405 KB – PDF)
Students conduct the following procedures:
- Measure temperature and pressure throughout the reaction between hydrochloric acid and sodium bicarbonate.
- Compare the experimentally determined number of moles of carbon dioxide generated to the number of moles that are theoretically possible and explain the discrepancies.
